A floating point division by zero by the calculation engine should in principle never occur, but there may be special cases where it could potentially occur anyway.
The error arise from an illegal operation performed by the engine and is typically caused by the input data to the model, which are apparently not as expected by the engine. It is extremely difficult for you as a user to find out exactly what is causing this error and typically, we would correct the problem and issue a hotfix to prevent that others meet the same problem at a point in time.
I would therefore recommend you to send your question together with a zip-file containing all model setup files to MIKE Support at e-mail; mikebydhi@dhigroup.com
It will then be possible to debug your model setup to firstly explain the reason for the illegal operation, and secondly to eventually prepare a hotfix if required.
